在阁楼待了九个月后，我安装了一台台式电脑。我有点怀疑这是否相关，但我不记得当时是这样。
启动需要六分钟左右，再过几分钟 GUI 登录屏幕就会出现，然后又过几分钟桌面管理器就会显示出来。
hdparm 给出以下输出：
# hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 2 MB in 3.75 seconds = 545.64 kB/sec
Timing buffered disk reads: 2 MB in 4.45 seconds = 459.91 kB/sec
然后我像这样运行 fstrim：
# fstrim -a -v
/home: 23.4 GiB (25130262528 bytes) trimmed
/boot: 397.1 MiB (416373760 bytes) trimmed
/: 5.2 GiB (5628624896 bytes) trimmed
hdparm 有所改进：
# hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 23604 MB in 2.00 seconds = 11811.48 MB/sec
Timing buffered disk reads: 54 MB in 4.27 seconds = 12.65 MB/sec
smartctl 输出：
# smartctl -i -A /dev/sda
